Acute and Chronic Disease - Difference, Defination & Examples

Acute and chronic diseases form the core of human health study, which explains to what extent the body reacts towards various kinds of illness. As opposed to acute diseases that are normally short-term and develop within a relatively short period, chronic diseases last for a long time and therefore require lengthy management. In major exams like NEET, AIIMS and paramedical, about 2-3% of the total marks are often based on this important topic from the CBSE Biology Class 12 Chapter Human Health and Disease.

• Imaging for example X-rays for arthritis
• Assessment of lifestyle, for example, dietary habits for heart disorders.

Tips, Tricks, And Strategies To Prepare For Acute And Chronic Diseases

• Study Aids: Create diagrams or comparison tables to help visualize and distinguish acute and chronic conditions.
• Mnemonics: Use memory aids such as "FAST" for acute and "LAST" for chronic diseases.
• Multimedia: Sometimes a series of videos or animations may help explain some abstract concepts about disease.
• Real-Life Application Link acute diseases, such as a cold, with everyday examples, and chronic diseases, such as asthma, to everyday examples.

Conclusion

Understanding the differences between acute and chronic diseases helps in managing health conditions and treatment approaches. Acute diseases are of short duration and curative in nature, such that once proper treatment is deployed, they are cured instantly.
